Description ricofernandes CLA 2011-04-08 14:23:53 EDT 
I have a web application running in Jboss that have lots of concurrent users. At a given time, lots of reports are generated.

In this scenario, sometimes reports run very slow! They appear to be waiting for something and then continue. I'm using a Servlet (almost equal to the reference servlet) to handle report generation.

Taking a dump of the threads running, I've noticed something strange:

org.eclipse.birt.report.engine.data.dte.ReportQueryBuilder.b uild(ReportQueryBuilder.java:256)
- locked <0x45a228> (a org.eclipse.birt.report.engine.ir.Report)
org.eclipse.birt.report.engine.data.dte.ReportQueryBuilder.b uild(ReportQueryBuilder.java:237)
- locked <0x45a228> (a org.eclipse.birt.report.engine.ir.Report)

Hi,

We need more detail dump info to analyze the problem. Could you please attach complete dump file? thanks.

According to current dump info, I am not able to reproduce the problem. I checked the relative source code, didn't find any clue about such a bug.

Set as worksforme. Please reopen it if there is more infomation.
